- increase verbosity with "-v"
- concat error messages (if there are several)
- handle 255 return code as warning (as it is the return code when any of the node is missing)
- read /etc/ctdb/nodes remotely (ctdb_check can be run on a non-ctdb host)

The pmda stuff is no longer built by default even if the headers are
available. To build, run "configure --enable-pmda".

The ctdb_statistics structure was recently changed. Update the PMDA to
dereference the new structure member names.

This is to verify that the fcntl F_GETLK call reports F_UNLCK if called
from a process already holding a lock. This is for example used by samba's
strict locking code in combination with "posix locking = true".

This plugin is GPL2 or greater as generally found in Nagios.
(this is obviously compatible with GPL3 or greater).

Rebase the CTDB PMDA from 1.0.114 to master:
- Add tevent and ctdb_protocol includes
- Handle latency metrics now stored under struct latency_counter
- Add new metric for the num_recoveries counter
(This used to be ctdb commit 2165a6f5117a71f9f97f46be9708fa34c037e17c)
Currently ctdb statistics are pulled in the PMDA fetch callback, which
results in a CTDB_CONTROL_STATISTICS call for each metric.
Do this once per fetch instead, and have the per-metric callbacks pull
data from the last counter cache.

Attempt to reconnect to ctdbd on fetch while it is unreachable.
We must provide our own queue callback wrapper, as ctdb_client_read_cb()
exits on transport failure.

The CTDB Performance Metrics Domain Agent (PMDA) is compiled when
Performance Co-Pilot (PCP) header files are present.
The CTDB PMDA periodically requests runtime counters from ctdbd (similar
to ctdb statistics) and exports these values via PCP for capture and
charting etc.

to have one single public ip address for the entire cluster.
this ip address is attached to lo on all nodes but only the recmaster
will respond to arp requests for this address.
the recmaster then runs an ipmux process that will pass any incoming
packets to this ip address onto the other node sin the cluster based on
the ip address of the client host
to use this feature one must
1, have one fixed ip address in the customers network attached
permanently attached to an interface
2, set CTDB_PUBLI_INTERFACE=
to specify on which interface the clients attach to the node
3, CTDB_SINGLE_PUBLI_IP=ip-address
to specify which ipaddress should be the "single public ip address"
to test with only one single client, attach several ip addresses to
the client and ping the public address from the client with different -I
options. look in network trace to see to which node the packet is
passed onto.

patches to smnotify to make it compile under AIX.
On AIX, we need to specify $(POPT_OBJ) explicitely
On AIX we can not use the -C flag to rpcgen since it is not implemented
On AIX we must explicitely force an #include of rpc/rpc.h in the idl
file since rpcgen does not automatically add it to the generated files
